To all whom ttf/nay concern:

Be it known that I, JAMES J. MURnocn, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Mechanism for Manufacturing Parquetry Flooring, of which the following is a specification.

My invention is designed to rovide mechanism for manufacturing flexi le parquetry flooring or wood carpeting from separable strips of wood. For convenience of handling parquetr flooring vconstructed of multiple pieces o wood, it is well known, that the pieces of wood constituting the flooring, or wood carpeting are usually assembled in a form, and when properly arranged, the pieces constituting the pattern are held tightly together, and coated on the bottom surface thereof with glue or other suitable adhesive substance, a fabric being spread and secured upon the glued surface of the strips, the atterri then being set to dry.

The object of my present invention is t0 provide machinery for assembling and securing together the separable pieces constituting a given form or pattern of the llooring or carpeting. I accomplish my object as hereinafter described and claimed and illustrated in the accompanying drawings, in which,

Fi ire 1 is a view in perspective illustrating eatures of my invention. Fig. 2 is a view in vertical longitudinal section. Fig. 3

. is a view in cross section.

The aim'of my invention is to accomplish the above desired results in a simple, economical and superior manner.

In the drawings a represents any suitable l suppot upon which is journaled a driving l sha rovided with a inion c meshing with a gear upon a driven s iaft e, upon which are mounted one or more eccentrics f. A feeding chute or runway is indicated at g to contain the strips h which are to be assembled.

Tliefeeding runway or hopper is located at one extremity of guide-ways or grooved tracks L upon each side of the machine upon which the extremities of the strips h may 3 rest and be automatically moved forward by one from the runway upon said grooved tracks, thereby moving forward all preceding strips u n the tracks simultaneously. Underneat the tracks, and forward of the feeding runway, is a roller Z revolving in a glue pot or chamber m by means of which glue or other suitable adhesive substance is applied to the under surface of the strips h, as they are moved forward. A roll or spool of suitable cloth or other fabric is indicated at n located beneath the tracks, the fabric when unwound from, its spool preferably passing over a tension roller p, and over -a contact roller g, whereby the fabric is brought firmly into .contact w1th the glued under surfaces of the strips and caused to adhere thereto. In advance of the contact roller g are one or more friction brushes r or similar instruments by which the fabric is smoothed out and pressed firmly in place .on the under surface of the strips.

The pressure of the adhesive roller Z may be effected in any suitable manner, as by a weight s upon a cranked end of the roller, the tension of the brushes 1' being also made adjustable,las by a weight t upon an arm u upon which the correspondin brush is engaged. Forward of the tension brushes I prefer to form underneath the tracks a drying chamber o, into which steam pi es w may extend, a blast apparatus being a so referably provided for said chamber, whic may consist of a pipe :c entering said chamber, said pipe connected with a blower y. The extremities of the tracks are preferably curved, as shown in Fig. 1, so that the stri s to which the fabric has been glued will e discharged from the tracks upon a table indicated at z, the reverse side upward. An attendant then simply cuts the fabric transversely between any two adjacent strips, leaving as many pieces or strips as may be desired for a single pattern or form assenibled. The strips thus being separable one from another in the completed flooring enables this severing to be made at any desired point. The curvature of the tracks should be of sufficient length so that the completed lloc shall be discharged therefrom, the clothnsxie uppermost, in order that the workman may separate the strips at any desiredpoint with a knife drawn between any two adjacent strips to form various sections or atterns as vmay be desired.

To holll the strips firmly down upon the ing whenever a roll of fabric gives out.

tracks and so that their adjacent edges shall be ressed so ti htly together so that no glue shal'be s rea( upon their adjacent edges any suitab e means may be employed, as for example, angle irons or pressure shoes 4 located above the extremities of the strips to hold the extremities' of the pieces firmly down upon the tracks. A friction clamping bar 7 is also secured above the pieces intermediate the extremities thereof, said bar being held in place by transverse bars 8. Beneath the pieces of wood toward the forward end of the machine, I prefer, also, to provide a friction clamping device to exert a friction tension upon the strips, a clamping bar 9 being shown bearing against the. strips from beneath, intermediate the extremities thereof. The pressure bar 7 preferably extends directly from the feeding chute or hopper g over and beyond the means for applying the adhesive substance, so that the separable strips or pieces of wood will be sulliciently retarded in their forward movement by the pressure mechanism to cause the advancing mechanism to maintain the adjacent edges of the successive strips in close and firm contact, thereby preventing the penetration of the adhesive substance between the edges of the successive strips.

It will be seen thatthe means for applying the adhesive substance to the under surface of the strips is located below the pressure bar 7. It will be evident also, that the means for applying the fabric to the under surface of the strips is located to perform its function after the application of the adhesive substance.

In Fig. 2, I have shown means for signal- This may be done in any suitable manner, as by a swinging arm 5, one extremity of which rests upon the fabric. When a roll of fabric has been exhausted, the arm 5 will drop, suitable electric mechanism 6 being provided with which the arm 5 forms electrical contact, thereby si naling the attendant.

It will e seen that only two attendants are required in connection with the machine, one to supply the hopper or feeding chute with strips or pieces to be assembled, and another to sever the work at the table z.. The tracks may obviously be of any desired length, the object being to have them of suflicient length to effectually dry the glued fabric upon the strips before it reaches the table z, with or without the heating or drying chamber.

The operation of the device will now be thoroughly understood, and need not be further explained.
